Subject: [PATCH V2] arm64: dts: qcom: sc7280: Update lpassaudio clock controller for resets

From: Taniya Das <quic_tdas@...cinc.com>

The lpass audio supports TX/RX/WSA block resets. Disable the LPASS PIL
clock by default, boards can enable it if needed.

Also to keep consistency update lpasscore to lpass_core.

Fixes: 9499240d15f2 ("arm64: dts: qcom: sc7280: Add lpasscore & lpassaudio clock controllers")
